How do I choose the device as it is not a but the cheapest is not a very expensive professional equipment and therefore wanted to find a middle ground. But as a previous reviewer I also realized that the seal on the connection for the compressed air hose went very quickly broken. With only light work (zeroing the vapor barrier) at Tacker began air from zutreten. Right after that there were problems with triggering the "surplus". This is very annoying when trying on the ladder to fix upside down something. For optical quality I can say that the device looks high, but the technology, this is by no means. For a handyman maybe recommended. For professional use, I would definitely take up a more expensive device.
